The Porsche 550 is a racing sports car produced by Porsche from 1953 until 1956. In that time only 90 Porsche 550s were produced, and they quickly established dominance in the 1.1- and 1.5- liter classes. The Porsche 550 is a mid-engine car with an air-cooled four-cylinder engine, following the precedent of the 1948 Porsche 356/1 prototype designed by Ferry Porsche. The mid-engine racing design was further developed with Porsche's 718 model; its advantages led to it becoming the dominant design for top-level racing cars by the mid-1960s.
The Porsche 550 has a solid racing history; it won the Nürburgring Eifel Race in May 1953, the first race it entered. The 550 Spyder usually finished in the top three in its class. Each Spyder was designed and customized to be raced.
A 1958 Porsche 550A Spyder sold at auction in 2018 by Bonhams for $5,170,000 (£4,115,763); it was the highest price for a 550 at auction.[1]
Engine and transmission
The Type 550/550 A is powered by an all aluminium 1,498 cc (1.5 L; 91.4 cu in) (85 x 66 mm)
The engine of the 550 is mounted in front of the rear axle making it mid-engined. This gives it a more balanced weight distribution, and allows for largely neutral handling. On the other hand, the low mass moment of inertia about the vehicle's vertical axis can lead to a sudden, difficult to control rotation of the car.
The first 550 had a fully synchronized 4-speed gearbox. Starting in 1956, a 5-speed gearbox was used, but its first gear only had to start and (like the reverse gear) had to be placed over a barrier and not synchronized. Excessive slip to the drive wheels in corners was prevented by a

History
Inspired by the
Racing history
The first three hand-built prototypes came in a coupé with a removable hardtop. The first (550-03) raced as a roadster at the Nurburgring Eifel Race in May 1953 winning its first race. Later that year the 550 took class wins in the
The 550 was also raced by privateers, who kept the type in competition after the works team had moved on to the 718 in 1957. The 550 was both a road and track car and it was common for privateers to drive it to the race track, race it, then drive it home.
Each Spyder was assigned a number for the race and had gumballs positioned on doors, front and rear, to be seen from any angle. On some 550s owned by privateers, a crude hand written number scrawled in house paint usually served the purpose. Cars with high numbers assigned such as 351, raced in the 1000 mile Mille Miglia, where the number represented the start time of 3.51am. On most occasions, numbers on each Spyder would change for each race entered, which today helps identify each 550 by chassis number and driver in period black and white photos.
Its successor from 1957 onwards, the
James Dean's 550
One of the first 90 Porsche 550s built was James Dean's, numbered 130 (VIN 550-0055), which was involved in a collision at the CA Rte. 46/41 Cholame Junction on September 30, 1955, resulting in Dean's death.[14]
As Dean was finishing up Giant's filming in September, 1955, he suddenly traded in his 356 Porsche Super Speedster at Competition Motors, for a new 1955 Porsche 550 Spyder on September 21, and immediately entered the upcoming Salinas Road Race event scheduled for October 1 and 2.[15]
A contemporary of Dean, the rising actor Tom Pittman also died prematurely when he crashed his Spyder over a cliff in 1958.[16]
